Measuring agreement in method comparison studies.
Agreement between two methods of clinical measurement can be quantified using the differences between observations made using the two methods on the same subjects. The 95% limits of agreement, estimated by mean difference +/- 1.96 standard deviation of the differences, provide an interval within which 95% of differences between measurements by the two methods are expected to lie. We describe ho...
متن کاملAssuring reliability in Qualitative studies: a Health Informatics Perspective
Assuring the validity and reliability of data is an essential component of data collection. While quantitative studies use certain statistical techniques such as ‘Cronbach Alpha’ values for a reliability index, in qualitative studies these type of measures are not widely available, and appear to be predominantly subjective. So, many studies, if at all probe this aspect, highlight what is normal...
متن کاملMeasuring agreement in method comparison studies with heteroscedastic measurements.
We propose a methodology for evaluation of agreement between two methods of measuring a continuous variable whose variability changes with magnitude. This problem routinely arises in method comparison studies that are common in health-related disciplines. Assuming replicated measurements, we first model the data using a heteroscedastic mixed-effects model, wherein a suitably defined true measur...
متن کاملEditorial: Selected Studies from Current Medical Informatics Research in Japan
This is the second Japanese issue of MIM, subsequent to the first publication last year [1-9]. We are very thankful to Prof. Haux, who gave us the chance to publish a Japanese Special Topic in Methods of Information in Medicine (MIM) again this year. We invited submissions for this current issue from the Japanese medical informatics community. Among quite a few papers submitted, we have careful...
